[R] Reshape

[jim holtman]

This gets you close; just edit the row names:

> x <- read.table(textConnection("X1,Y1,hr1,hr2,hr3
+ X1,Y2,hr1,hr2,hr3
+ X1,Y3,hr1,hr2,hr3
+ X2,Y1,hr1,hr2,hr3
+ X2,Y2,hr1,hr2,hr3
+ X2,Y3,hr1,hr2,hr3"), sep = ',', as.is = TRUE)
> closeAllConnections()
> require(reshape2)
> x.m <- melt(x, id = c('V1', 'V2'), stringsAsFactors = FALSE)
> t(cast(x.m, V1 ~ V2, fun = as.character))
      X1    X2
Y1_X1 "hr1" "hr1"
Y1_X2 "hr2" "hr2"
Y1_X3 "hr3" "hr3"
Y2_X1 "hr1" "hr1"
Y2_X2 "hr2" "hr2"
Y2_X3 "hr3" "hr3"
Y3_X1 "hr1" "hr1"
Y3_X2 "hr2" "hr2"
Y3_X3 "hr3" "hr3"
